Cable Cross Section Calculator
Calculate the minimum required conductor cross-sectional area (mm²) based on current, cable length, and voltage drop limit according to IEC 60228 and national standards.
Recommended: Lighting ≤3%, Power ≤5%
Results
| Min Calculated Area | — mm² |
| Recommended IEC Size | — mm² |
| Actual Voltage Drop | — V (—%) |
| IEC Ampacity Rating | — A |

Formulas
Single Phase / DC: A = 2 × ρ × L × I / (ΔU)
3-Phase: A = √3 × ρ × L × I / (ΔU)
ΔU = System Voltage × Drop %
